There aren't a whole lot of good healing cards, and it doesn't seem worth 6 XP just to take some otherwise bad cards and make them good (you could just play the good cards to begin with). Still, this seems like it will get real value out of the occasional healing card that was already playable. Obviously this should be strong in Carolyn Fern and Vincent Lee. Some other examples for the not-healing-focused investigators:
- Book of Psalms was already a reliable blessing enabler with healing as a side effect. This will provide significant utility to a blessing deck.
- Hallowed Mirror is arguably the best dedicated healing card at 0xp. Soothing Melody doesn't cost any resources or cards; two healing for one action is actually a pretty good rate. This lets you benefit (maybe even more than normal!) when you don't have anything to heal.
- Empty Vessel, like most of these, heals you while also doing something powerful that you wanted anyway.
- Deny Existence, while expensive in terms of XP, was already one of the best dodges in the game. Again, a substantial improvement on something you weren't really playing for the healing.
- Lily Chen's Discipline. The active effect is already quite potent and reusable, and guardians can end up with periodic downtime to use it.
What most excites me about it, though, is that it might kind of bail out Shrewd Analysis. Two of the otherwise stronger Researched cards have healing upgrades which are basically duds (Ancient Stone and Strange Solution). Now, if you get one of those, you can spend some of the XP you saved with Shrewd Analysis to turn them into playable cards. All three Ancient Stone upgrades seem actively good now, and all four Strange Solution upgrades seem at least playable (Strange Solution is still obviously the best). I still don't think Shrewd Analysis is optimal, but I still like to see it get some indirect help since it's a lot of fun.
